To all whom, it may concern.- I .Be it known that I, ERNEST DE Wi'rr R.GA'IRDEN, a citizerrol theUnited States, resid- 5 ing at Tarrytown, inthe county of Westchester and State of New York, have invented certainnew and useful Improvements in Artificial Dentures; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enableothers' skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in artificial dentures, and moreparticularly to bridgework; and it consists in certain novel features oiconstruction, combination, and arrangement ot parts hereinafterdescribed The object oithe invention is to provide a simple, practical,and oil" ient means for sethcir metal backings or work and the like.

The above and other objects, which will appear as the nature oi" myinvention is hot tcr understood, are acemnplished by means oi theemistruction illustrated in the accompanying drawings, in which-- Figure1 :rpcrspectivc' view of an embodiment oi my invention, showing a groupof bicuspids and molars. Fig. 2 is a longitudinal View through the same.Fig. 3 is a transverse sections l. view, and Fig. 4 is a perspectiveView, of one of the porcelain biting surfaces or faoinrs.

Referring to the drawings by numeral, '1. denotes my improved artificialdenture or bridge consisting of two bicuspids 2 23 and two molars i 5,arrang cd in consecutive order, the outer bicuspid 2 and molar 4 beingin the form oi the usual crown lo fit over natural teeth or the stumps:thereof. These by a-metayl bridge 6, winch Forms backin gs or caps? 8for the inner .2 raid 3 and the inner molar 4, said bicusu molar o 4having outer porcelain bitcavities 11 and intheir inner faces withgrooves or notches 12 to receive the cement which secures them in theirmetal caps or holders? 8. The latter have their surrounding edges bentinwardly to a slight extent, as

shown, and in their central portions are sol-- dered or-otherwisesecured metal loops 13,

which are adapted to fit into the cavities or the construction andoperation of the invention will be readily understood without requiring,a more extended explanation.
